In 1857, a steamship loaded with 30,000 pounds of gold sunk off the coast of South Carolina. Odyssey Marine Exploration, Inc., a company that specializes in deep-ocean exploration, is attempting to retrieve the sunken treasure from the so-called SS Central America (pictured here in a contemporary depiction of the ship's sinking).
Here are some photos of the expedition to retrieve sunken gold from the famous shipwreck.

By using advance robotics to explore deep-ocean sites, the Odyssey crew is able to work around the clock with limitless bottom time. Above, Odyssey's remotely operated vehicle (ROV) ZEUS returns to the surface following work on a deep-ocean shipwreck site.

The Odyssey Explorer serves as Odyssey's principal state-of-the-art deep-ocean archaeological platform.
Odyssey's eight-ton Remotely Operated Vehicle (ROV) ZEUS is launched from the ship's deck. The ROV descends to the ocean floor to conduct work on a deep-ocean shipwreck sites while operation is directed by the archaeologist and project manager aboard the Odyssey Explorer.
